1 c all whom it may concern i I Be it known that I, WALTER S. ROBERTS, a

' citizen of the United States, and a resident Accentuating Devices for Controllers, of

which the following is a specification. 1

of Edgew ood Park,- in the county of Allegheny and State of Pennsylvania, have 1nvented-a new and useful Improvement in My invention relates to controllers and particularly to the means for accentuating the various controller positions. .7

Y a device for accentuatingthe various 'posii-' tions of a controller that shall be simple and compact' in construction and reliable, eflective and positive in operation." q Theaccentuatm devices of the controllers now in service em dy star wheels and roll- 1 ers resiliently held in engagement with the star wheels. The teeth formed in the periphery of the star wheel are so shaped, in accordance with the sizeof the cooperating roller, that only a small forceserv'es to move j the drum slightly and, in some cases, a small.:

oscillatory movement of the controller may be directed without'moving it from one po- I sition to another.' .In such accentuating'devices, it .is diflicult to hold the controller drum in a fixed position and to have definitely marked controller positions. 1 j I Ina controller constructed in accordance with my invention, the accentuating device is provided with means for positively mark: a ing the various controller positions and preventing any oscillatory movement oftheconvtroller drum. a V The single figure of the accompanying,

' drawing is a plan view of acontroller pro- .vided with an accentuating device constructed in accordance with my invention.

7 Referring to the accompanying drawing, a controller embodies a statlonary frame 2, a

"cover: 3 attached thereto, and a shaft 4 having a control drum 5 and a. star wheel 6 rigidly'mounted thereon. The control drum 5 is provided with the usual contact segfments 7flwhich selectively engage contact fingers 8f I A lever 9, which is disposedadjacent to the star wheel 6, is pivotally mounted on a projection 10 which extends from the frame. '2. A triangular 'block 11' is pivotally mounted on thelever'9 near one endthereof, N

7 cent teeth 12 of the star wheel 6. A s

13 is attached to the opposite end of the lever 9 for maintaining the triangular block 11 in en agement with the star wheel.

One object of my invention is to provide in any convenient manner, and is adapted to engage any one of the spaces between'adjapring nasmuch as the triangularblock; 11 has stra ght sides and the teeth 12'of'thestar wheel are so formed as to provide angular SPiLCGS therebetween which fit such straight slc es,

to be covered by the appended claims.

I claim as my. invention 1.-In a controller, arotatably mounted Patented a gie 1 920.

star wheel having angular recesses, and a I block of polygonal shape adapted to be resiliently held in any one of the recesses of said star wheel for accentuating the various controller positions. v V

2. V In a controller, a wheel having angular recesses in the periphery thereof, a pivotally .mounted block of'polygonal shape, and re-' silient means for holding said block in any one of the recesses of said wheel.-

3. In a controller, a star wheel, a pivotally mounted block of triangular shape, and means for holding the block in contact with said star wheel.

i 4. In a controller, an accentuating device embodying a star wheel having angular recesses, a pivotally mounted arm having a block of polygonal shape pivotally mounted near one end thereof and having two of its sides conforming-to the sides of each of said recesses, and means for holding the block 1 engagement with the star wheel.

5.v Ina controller, a shaft having a contact drum and a'star wheel mounted thereon, a

lever pivotally mounted adjacent to the star wheel, a block'of triangular shape pivotally:

mounted on said levernear one end thereof, and resilient means attached to sald lever for maintaining the triangular block in en- 1 'gagement with the star wheel.

v, 6. In a controller, means for accentuating' so" I having 'a plurality of angular recesses, and :1 member having it plurality of angulam pro .jections severally adapted, to, oeoupy any one of said recesses to accentuate theposi'tions of sgugl cznn.

8. In a conflroller a rotatalile a'ccentuating cam having a plurality oi: peripherally po$ ed angular reoesses and a cent mlly, fpi otg ally jmounbeclimexnber haying @he eon 'gu- [ration of an equiangular polygon, the vertices of said polygon being severally adapted to be moved rinto any one of saic'l recesses upon a forwardor backward! movement "of sai e eexxtllating lam,-
